Don't trust a shop with your spoke measurements. Unless you're really picky, just use the quoted ERD of the rim, and look up/measure the hub flange width/hole circle (or whatever you want to call them).
I like this one - easy to quickly compare various factors, and it's as accurate as the usual suspects like Rinard et al.
